As unstable eighteen-F decays, it releases positrons. Within about two mm of journey from their origination web site in tissue, positrons collide with electrons and release gamma Power (photons). The photons strike scintillator crystals housed in a tool that encircles the affected person. Crystals Utilized in modern imaging devices fluctuate by company, Each and every with its own photon detection yield and determination; a common crystal type employed for PET is lutetium oxyorthosilicate.
